slope = $0$ y-intercept = $-2$ Refer to the image below for the graph.

Work Step by Step

RECALL: The graph of an equation in the form $y=k$ is a horizontal line. It has a slope of zero and has $k$ as its y-intercept. All the points on the graph of this line have $k$ as their y-coordinate. Thus, the graph of $y=-2$ is a horizontal line, has a y-intercept of $-2$, and all the points on the line have $-2$ as their y-coordinate. Plot the y-intercept point $(0, -2)$. Plot another point whose y-coordinate is $-2$. (e.g., $(3, -2)$). Then, connect the two points together using a straight line. (refer to the attached image in the answer part above)
